Any info on this racquet? It's green... 80/20 composite written on it. What's the 20, aluminium, fiberglass? HOw does it play? Wtah are the specs? Is it a solid racquet or just a cheap old frame (depends on that composite materials, I guess)?

by the way, does this 600 means 93 qin? looked bigger, but what do I know...

is there any way I can be sure that there's no 20% aluminium in there? I would probably be able to tell if it was one of those cheap pure alloy sticks, but 20% would manage to remain hidden untill my arms started to hurt...

Thanks. I'm considering buying either this or the Yonex RDX 500 MP. Both at about the same price. Prince is cheaper and maybe the paintjob is in better conditions, but it would need new strings and a bigger grip size (nothing too difficult) so the price would be about the same... Could you compare them to the NBlade MP (my spare racquet wich I would replace and give to a friend)?
